Application filed January 16, 1928. Serial No. 246,954.

This invention relates to a weft carrier magazine in anautomaticweftreplenishing loom, suohasis shown and described-inmy prior applicationSerial No. 212,996, filed Aucarriers are'stored in separate compartmentsin "a magazine, and each compartment is moved downward to present a weftcarrier in transfer position upon indication. of weft exhaustion. p

v It is the object of invention tojimprove and simplify themechanism fordepressing a selected compartment to delivery. position.

Another feature of my inventionrelates to the provision of improvedmeans for holding 'acompartment elevated above normal position forrefilling, atthe same time rendering v inoperative the mechamsm forlowering the compartment to delivery position. r

- mentsand combinations of parts which will be hereinafter described.and-more particularly pointed out in the appended claims. a

elevated position for refilling.

' For selectivelydepressing the "compartments, I PlOVlClQ eachcompartment with a tends apivot-stud 32 in the member 25. The lower endof the latch is provided with a. 7 lug orpro yection 33 and the upperend of the latch is engaged by-a spring 34Which holds vided with ashoulder or projection-36nd? jacent th'elatch3 0. a I orslide 40 (Fig.2) 1s mountedinsupports-4l onthe fr'ame 20 and is, yieldiugly moved totheleft'in Figs. 1 and Qty :1 light coil spring 42., The offset end 432) of the indicating slide '40is posi- 'tioned for engagement with a bar44 actu-' ated and controlled the weft detecting my, prior application.

The indicatorslide 40 1s with a *latches 3O, moving them from theposition V mechanism of the loom, as fully set forth'in shown inLF, 6tothe position shown injFig.

.75. Such movement advances the lug ,orprothe drop boxes, as.iscustomary in such weft latches 30 ,will be engaged by an actuating arm46 at anygiven time. The latch thus engaged will always correspond tothe compartment having weft carriers similar to the run substantially;exhausted.

' The rock sh 48'i( Fig.-8) connected by a'link, 49 to a lever pivotedat 5'1. and having a cam-roll 52 .POSllJIOIlQCl in the groove 53 of {acam 54 mounted onthe usual camlorbottom shaft 55, which snakes onerevolution f0r..;each two provided with an arm picks of the loom. LThecar'n is soshaped that i j the ineinberj46 will begiven alternaterocking 1 movements, the first. jdownward ;.movement f I y beingrelatively short and the second downward movement being of substantiallygreater extent, while the upward movement of travel is the same in eachcase. The method of operation of the latches 30, the indicator slide 40,and the actuating members to will be hereinafter described.

The upright bars or members 25, movable with the compartments 21, arepreferably provided with notches 56 (Fig. 1) yieldingly engaged bysprings 57 or 58 which hold the compartments yieldingly in normalposition. The spring 57 between two adjacent compartments may preferablybe made as a double spring, while single springs 58 are provided for theouter compartments.

When a compartment is depressed for weft replenishment, its spring 57 or58 is moved yieldingly out of theupper notch 56 and slides along thestraight upper end of the corresponding bar 25. If, however, it isdesired to refill a weft carrier compartment, the compartment is pulledupward manually to the positionindicated in broken lines in Fig. 1, andthe correspondingspring 57 or 58 engages the lower notch 56 and holdsthe compartment raised during replenishment. \Vhile in raisedposition,the compartment is removed from the path of operation of thecolor slide or indicator 40, as indicated in Fig. 4, so that thatparticular compartment will not be indicated or depressed during therefilling thereof.

The operation'of the indicating and depressing mechanism is as followsUpon inclication of weft exhaustion by the detecting mechanism (notshown), the bar 14 2) will be moved to the dotted line position in saidfigure, and when swung forward in this position, it will engage the end48 of the inclicator slide 40, causing the latches 30 to be moved fromthe position shown in Figs. '3 and 6 to the position shown in Fig. 7with their projections 33 extending beneath the actuating-arms 46.

The shaft4l7 ismovable endwise fixed re lation to the movements of thedrop boxes, so.

that one of the arms 16 will always be aligned with the latch 30 of thecompartment corresponding to the running shuttle. The arms '46 thenreceive their short downward movement from the cam 54,- as previouslydescribed, which short movement is sufiicient to slide the latch 30downward on its supporting bar 25 t0 the position indicated in Fig. 8,such movement being permitted by the pin and slot connection between thelatch and the bar.

This movement causes the lower end of the latch to project beyond ashoulder 60 formed in a recess in the bar 25, which shoulder holds thelatch outward in operative position while the arm 16 swings upward asin-' dicated in Fig. 9. The latch 30 thus holds the indication, in casethe drop boxes should'be supporting bar 25 will be moved downward,

as indicated in Fig. 10, depressing the corresponding weftcarriercompartment to position to deliver a weft carrier to the transferlnechanini, as fully described in my prior application. At the beginningof the return upward movement of the arms d6, the opera tive arm willfirst engage the latch 80 and slide it upward on its pivot stud 32 tothe raised position of 3, thus clearing the abutment 6 The arm 16 willthen engage the lug 36 on the corresponding slide bar or support 25 andwill thus restore the parts to j the normal or initial position of 6.

I have thus providedvery simple mechanism for receiving anindication ofweft carrier exhaustion and for preserving the indication until thereturn of the corresponding shuttle and weft carrier to the magazineside of the m. 1 have also provided meansfor holding a weft carriercompartment elevated for refillin and for renderingthe depressingmechanism inoperative with respect to a compartment thus elevated.

Having thus described my the advantages thereof,-I do not wish to belimited to the details herein disclosed'otherwise than as set forth inthe claims, but what Iclaim is p 1. In a weft replenishing magazine, aframe, a plurality of substantially vertical weft carrier compartmentseach separately movable in said frame, selective means to invention andi move a compartment downward to weft car rier delivery position andmeans to hold a selected compartment elevated above normal position forrefilling,"said selective lowering means beinginoperative with respecttoa compartment thus elevated but being restored to operative relation tosaid compartmentiby sition. 1

5. The combination in a loom as set forth in claim 4, in which the latchhas a pin and slot connection to said compartment and is movabledownward independently of its compartment by the short stroke of saidactuator, and

in which means is provided to holdsaid latch in engaging position untilagain engaged by said acuator on the long depressing movement thereof.

6.
